Abstract Developing efficient catalysts to convert CO 2 into value‐added chemicals is valuable for reducing carbon emissions. Herein, a kind of novel thiolate‐based ionic liquid with sulfur as the active site was designed and synthesized, which served highly catalyst reductive N‐functionalization by amines hydrosilane. By adjusting pressure, various N‐formamides N‐methylamines were selectively obtained in high yields. Remarkably, at loading 0.1 mol %, N‐formylation reaction N ‐methylaniline exhibited an impressive turnover frequency (TOF) up 600 h −1 , could be attributed roles liquids activating hydrosilane amine. In addition, control experiments NMR monitoring provided evidence that reduction yielded formoxysilane intermediates subsequently reacted form N‐formylated products. Alternatively, further react amine produce 4‐electron‐reduced aminal These products crucial N‐methylation reactions.

This work suggests an engineering methodology for catalytic 2D materials to achieve more efficient systems. Zinc gallate (ZnG), a Lewis acidic material with thin morphology, can easily form aggregates through layer–layer packing. Inner parts of ZnG would have difficulty in interacting substrates. By coating hollow microporous organic polymer (H-MOP) supports ZnG, the performance be enhanced due facilitated contact substrates Zn species shells. H-MOP@ZnG-2 optimal showed much reductive carbon dioxide fixation amines formamides compared ZnG. Various utilized formamides. In addition, recyclability, maintaining its five successive reactions.

A proficient heterogeneous catalytic system for the photocatalytic N-formylation reaction of amines and cyclic carbonate synthesis from epoxides using CO2 as a carbon source under ambient conditions has been documented. sophisticated approach established current process, aiming successful production formamides carbonates with high levels selectivity efficiency by adjusting several variables such solvent, time, well light involved in reaction. We have synthesized two distinct catalysts, T-COF N-COF, along g-C3N4 heterojunction, demonstrating outstanding performance. Compared to g-C3N4@N-COF, g-C3N4@T-COF photocatalyst showed significantly better light-driven formation other suitable at room temperature. The g-C3N4@COF photocatalysts can be recycled used multiple times without any noticeable decrease efficiency.
